Abstract

A process for evaporating or removing solvent from a product dissolved in a solvent with components of varying volatility and for recovering at least one fraction of the solvent enriched with at least one more volatile component by means of an evaporation plant which comprises at least two evaporation stages through which the product flows in parallel flow or in counterflow to the heating vapour and/or vapours of the product and at least two evaporators through which the dissolved product flows one after the other, not necessarily but preferably directly, in one evaporation stage, in which the at least two evaporators through which the product flows one after the other in the evaporation stage are heated in parallel with heating vapour and/or vapours of the product and in which the vapours containing a concentration of at least one more volatile component from the evaporator through which the product flows first in this evaporation stage are condensed within the evaporation plant in order to recover a current of liquid containing an enriched concentration of at least one more readily volatile component.
